This is the appeal of Runescape. Jagex (before all of RuneScape gold this f***ed up) and The Gower Brothers deserve a huge pat on their back for a job well performed and having a lasting impact on a large percentage of the world's population. The last 30 seconds of the Newbie Melody wave goodbye to those illustrious memories and put our childhood into a cardboard box in our heads.
The game needs to release quests that can live up to, or even exceed the earlier quests. While Guthix Still Sleeps is still my top quest and it will be six-years old next month.
In the present, I believe that quests tend to be too focused on their environment (Freneskae), and there have been a few quests that were released for this purpose The entire quest was created in order to return Zaros. The quest was incredibly popular. There was nothing mysterious surrounding the end of the quest, and it was better to be aware of what the outcome would be before you even began the quest.
There was a huge banner proclaiming "Zaros is back!" even in the lobby. And I do agree with you about Plagues End - No revolution could be planned in five minutes and successfully completed in just two minutes, with the highlight of kicking down a door and slapping every person in the opposition one-handed.
What I'd like to see to see is quests released with a slower pace, but those quests be good. There hasn't been any quests released that ranks in my top favourite quests since 2009. (The Chosen commander) I was confused by their second quest The Mighty Fall. Then they followed it up with a quest on the Dorgeshunn. It was not clear to me why they managed to accomplish this. I felt they should have resigned and gotten rid of the Cave goblins entirely. It was a typical quest, with nothing that made it any more memorable. 3 boss fights and running through an area designed specifically for buy old school runescape gold the quest.
